I have a question regarding slideshow. I have been able to extract some common calls out into functions, as long as there is a single expression in the function ((define (letk) (tt "let ")) as example). But if I have multiple expressions I keep getting errors. Does anyone have any idea?

@yefo.akira the tt function produces a pict, which gets added to the slide. It doesn’t have a side effect.

Oh, of course. Which is why when I am executing multiple (tt) only the last one is being put on the slide. So then I need to group by something like (vc-append)? Or is there a function that groups expressions without modifying the output?

@yefo.akira yeah, something like vc-append is what you want

Works. Cheers :slightly_smiling_face:
